ABSTRACT
INTRODUCTION:
Little is known about the imaging of omental pathologies. The aim of the current study was to determine the value of B-mode ultrasound (B-US), contrast-enhanced ultrasound (CEUS), and ultrasound-guided core needle biopsy for the differential diagnosis of benign and malignant omental pathologies. PATIENTS ANDMETHODS:
A retrospective evaluation (2008-2017) was performed in 44 patients (median 65,5 years, mean 64 years [47-83], 27 male, 17 female) with histological (40/44 [91â%]) or cytological (4/44 [9â%]) proven omental lesions. Clinical signs and final diagnosis, size, B-US and CEUS findings, and complications were analyzed.RESULTS:
Omental thickening was in nâ=â36 (81.8â%) of the cases malignant (mOL) and in nâ=â8 (18.2â%) benign (bOL). Twenty-six (59.1â%) patients had ascites (nâ=â24 [66.7â%] mOL, nâ=â2 [25â%] bOL). The average tumor thickness was 23âmm (24âmm in mOL, 20âmm in bOL). Interventional complications were not observed.DISCUSSION:
The majority of omental lesions are malignant. The differentiation between a malignant or benign cause of thickening is not possible by any imaging method. CEUS is helpful to determine vital tissue before biopsy. Ultrasound-guided core-needle biopsy allows final diagnosis of omental thickening if >â10âmm and should be performed prior to the more invasive and complicative diagnostic laparoscopy.
